I kindly give you a machine that makes your dreams come to life. Overjoyed, you accept it and have wonderful dreams for 20 years. However, I secretly use the control button and give you a nightmare where you fall... and fall... and fall... and fall... and wake up before you hit the ground. But I make it so you don't wake up.
i erase it from time by killing you when you were a baby by using Emmet Brown's time machine(it is a car) that has to go 88 mph while having the mr fusion on and eating trash or using plutonium
You are instantly shot once you come into view on top of the hill by a criminal. He further steals your 100$ and runs off.
I take the candy cane and throw it into acid.
